Time taken by the body to move through a distance of 12 m is 2 s
Explanation:
using the equation for force
m= mass= 1 kg
F= force= 6 N
a= acceleration=
6= 1 a
a= 6 m/s²
Now using the kinematic equation,
d= distance= 12 m
V= initial velocity=0 as the object is at rest initially
12= 0(t)+ 1/2 (6) t²
t²=4
t= 2 s
There are two rules of reflection for the concave mirror:
1)<span>Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.
2)</span><span>Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
Also, keep in that for concave mirror center of curvature is 2f.
Using these two rules we can construct the image.
You should always use these two "special" rays, I will mark then 1 and 2 on the picture.
From the picture, we can see that if you place the object between the focus and vertex you get the virtual image.
The answer is: object should be between the focal point and the vertex</span>
